Ready access to 3-amino-2,3-dideoxysugars via regio- and stereo-selective tandem hydroamination-glycosylation of glycals

A highly stereoselective BF3 center dot OEt2-promoted tandem hydroamination-glycosylation on a glycal scaffold has been developed to form 3-amino-2,3-dideoxysugars in a one-pot procedure. This efficient multicomponent reaction protocol offers simplicity and general applicability to a broad range of variations on each component.
